The problem is that Neil wants focus-priority AF-C, so that when he's tracking a moving subject, he can hold the shutter release and AF-ON, and have the camera release the shutter when it detects that focus has been achieved. That's not actually compatible with AF-C focus-and-recompose, since the shutter may not release if the recompose moves the AF bracket over something oof.
My workaround for this is to have an action bank set up with focus-priority AF-C, and a general purpose bank with release-priority AF-C. I track action in the former, and focus-and-recompose using the latter. They can't cross-over, but U1/U2 on the mode dial makes this a reasonable workaround (actually, not a workaround for me, since I do this on my Dx00 bodies as well, and don't use AE-L/AF-L for anything (actually I might have set it for virtual horizon on my D300s). I use AE-L for AF-ON on D7K).
